Calculate E _ cell ^ for the following. Zn _ ( s ) | Zn _ (1 M ) ⁺⁺ | | Pb _ (1 M ) ⁺⁺ | Pb _ ( s ) if E _ Zn ^ ^ =-0.763 ~V and E _ Pb ^ o =-0.126 ~V
Options
- A0.637 ~V
- B-0.530 ~V
- C-0.889 ~V
- D0.789 ~V
Correct answer
A. 0.637 ~V
Step-by-step solution
For the given cell, Zn acts as anode and Pb acts as cathode. E _ cell ^0= E _ cathode ^0- E _ anode ^0= E _ Pb ^0- E _ Zn ^0=-0.126 ~V -(-0.763) V =0.637 ~V
